How often does your grass need mowed?

How often does your grass need mowed or cut? You notice I said "need". Our grass has needed cut within less than a week of it being mowed for the last month now. I can't believe how much it is growing this year. Maybe it just seems that way, because it has been a year since growing season. And then of course, in the summer when it gets really hot, I'll probably be wondering why it isn't growing enough. LOL
What about you? Does it seem like your grass has been growing a lot here lately? Does it need mowed pretty quick, or is it just average?
